UNITED STATES PATEN'I OFFICE CRAIG I1. DOTSON, F WASHINGTON, PENNSYLVANIA LEER FEEDER Application filed August 26, 1926. Serial No. 131,668.

This invention relates to mechanisms for wheel 12 keyed to a vertical shaft 13 which mechanically feeding glassware to an annealis mounted in bearings 14 and 15 on the ing furnace, and has for its object to provide bracket 8; also keyed to shaft 13 is a gear a relatively simple and compact machine by wheel 16 which meshes with a gear wheel 17 5 which the ware may be arranged in the leer in of the intermediate gears 1718; the latter .a regular and orderly manner. in turn meshing with the driven gear 19.

These guldes or chutes plate 6 which is provided with leveling screws 3031 pass through openmgs 32 in the leer 45 7 and to which an upwardly arched bracket door 3 and extend ust above the conveyer 2 8 is secured.

The worm gear 11 operates a worm the heat therein.

In order that these guides or chutes 30 and 31 may be oscillated to uniformly distribute the ware over the leer conveyer 2, the guide plates 28 and 29, of which the chutes are an.

integral part, are connected by means of a rod 33 which has its ends secured to wrist pins 34: and 35 on the under side of the guide plates. This connecting rod 33 carries a cam roller 36 intermediate its ends which cooperates with a uniform speed cam 37 keyed to a shaft 38. By a train of reducing gearing including the gear wheel 39 fixed to the shaft 40, gear wheels 41 and 12 operatively connected together but loosely mounted on shaft 13, and gear wheel 44 fixed to shaft 38, the cam 37 is slowly rotated so as to cause an oscillation of the chutes across the conveyer.

As the chutes slowly traverse the leer conveyer 2 the ware is fed therefrom, and this feeding operation is accomplished by means of pushers which are removably secured to pusher rods 51 in order to suit ware of varying dimensions. The pusher rods 51 are bolted to slides 52 which are mounted on slide rods 53 the latter being anchored to the rear ends of the guide plates 28 and 29 as indicated by numeral 54. Reciprocating movement is imparted to the slides 52 and pushers 50 by means of links 55 which are attached to wrist pins 56 and 57 on the slides 52 and the upper discs of bosses 2627. Obviously, therefore,

as the feeder is operated through main drive shaft 9 and the related gearing, the pushers 50 are reciprocated to eject the ware from the discs 21 and 22 after it is carried around and brought into contact with the guard plates 58 which are adjustably mounted on the plates 28 and 29 by means of theslots 59 and set screws 60. This adjustment adapts the feeder to accommodate ware of various widths.

The conveyer 23 is driven by means of gear wheel 16 which meshes with an intermediate gear 61 which in turn meshes with a gear wheel 62 fixed on shaft 63. Also fixed on shaft 63 is a mitre gear 64 which meshes with a mitre gear 65 carried by the horizontal shaft 66, and on which is fixed a sprocket wheel 67 for operating the conveyer.

In the operation of the feeder in conjunction with a single forming machine, the articles will be carried along by the conveyer 23 and will be alternately switched over by the deflector 25 to one disc 2122 and then to the other. The articles are then carried in the direction of the arrows (Fig. 1) until they the cam 37 and connecting rod 33, and thus serve to arrange the articles in rows trans-- versely of the leer as indicated in Figure 1. If it is desired to employ the feeder with articles of a different width from those shown the width of the chute may be altered by means of the adjusting screws 60.

Where the apparatus is used with two form- -ing machines the articles will be placed on machines, or from a single forming machine,

to a leer in such a manner that the ware is maintained in two segregated groups; which will feed articles while lying on their sides or in upright position; and which is adjustable for articles of varying sizes.

In accordance with the patent statutes I have described what I now believe to be the best embodiment of the invention, but it will be apparent that various changes and modifications may be made without departing from the spirit of the invention; allsuch I aim to include within the scope of the appended claims.

WVhat I claim as new and desire to secure by Letters Patent is:

1. A leer feeder including a plurality of guides for delivering glassware to a leer, means for oscillating said guides to arrange the ware in the leer, a rotatable member associated with each of said guides, a conveyer common to said members, and means adapted to feed the ware from said members to said guides.

2. A leer feeder including a plurality of guides for delivering glassware to a leer, means for oscillating said guides to arrange the ware in the leer, a rotatable member associated with each of said guides, means for feeding ware to said members, and reciprocable elements adapted to feed the ware from said members to said guides.

3. A leer feeder including a plurality of guides for delivering glassware to a leer, mean-s for oscillating said guides, a rotatable disc associated with each of said guides, a reciprocable pusher associated with each disc for feeding the ware from the discs to the guides, a conveyer arranged between the discs, and a deflector for distributing the ware from said conveyer to said discs.

4. A leer feeder including a plurality of guides for delivering glassware to a leer, means for oscillating said guides, a rotatable disc associated with each of said guides, a reciprocable pusher associated with each disc for feeding the ware from the discs to the guides, a conveyer common to the discs, and

5. A leer feeder including a guide for delivering glassware to a leer, means for moving said guide back and forth, a. rotatable disc associated with the ide, and a reciprocable pusher for dellvering the ware from the disc to the guide.

6. A leer feeder including a guide for delivering glassware to a leer, means for oscillating said guide, a conveyor for transporting the ware to the leer feeder, a rotary disc receiving the Ware from said conveyer, and a reciprocable pusher for delivering the ware from said disc to said guide and then to g the leer.

7. A leer feeder including a conveyer for transporting the ware to the leer feeder, a
